Effect of Climatic Conditions on Durability of Clayey Soil Stabilized with Lime

Tikrit Journal of Engineering Sciences, 2011
Durability is one of the most important subjects in the soil stabilization. Since there is no specifications concerned the durability of lime-stabilized soils, several factors were selected to show their effects on the durability, namely: wetting, drying,

Coupling of Physical Protection and Molecular Composition Drives Carbon Sequestration Divergence in Soils Planted With Different Tea Varieties

Land Degradation &Development, EarlyView.
ABSTRACT Tea plantations represent significant carbon (C) sinks in agricultural landscapes, yet how variety‐specific organic inputs are associated with the molecular composition and stability of soil organic carbon (SOC) within aggregate hierarchies remains unclear.

Experimental study on moisture migration law of soils under dynamic slaking conditions

Yantu gongcheng xuebao
Understanding the moisture migration mechanisms in railway subgrade soils under dynamic slaking (D-S) is critical for elucidating the formation mechanisms of frost heave and mud pumping defects in heavy-haul railways.

Towards a better understanding of hot-mixed mortars for the conservation of historic buildings: the role of water temperature and steam during lime slaking

Heritage Science, 2021
According to various historic accounts and material evidence, the practice of producing lime mortars by mixing the quicklime with the sand (i.e. hot-mixing) before first slaking it with water was much more common in the past centuries than appreciated by

The Material Basis of 18th‐Century Meissen Porcelain

Archaeometry, EarlyView.
ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

Mortars From Punic and Hellenistic–Roman Solunto: Materials, Formulations, and Technology

Archaeometry, EarlyView.
ABSTRACT This study presents an archaeometric investigation of 18 hydraulic rendering and bedding mortars from Punic and Hellenistic–Roman Solunto (NW Sicily). The research aimed to characterize raw materials, reconstruct manufacturing sequences, and evaluate technological proficiency through mineralogical and petrochemical analyses.

Modeling, simulation, and analysis of a reactor system for the generation of white liquor of a pulp and paper industry

Brazilian Archives of Biology and Technology, 2011
An industrial system for the production of white liquor of a pulp and paper industry, Klabin Paraná Papéis, formed by ten reactors was modeled, simulated, and analyzed. The developed model considered possible water losses by the evaporation and reaction,

Subregion‐specific perineuronal net remodelling in the dorsal hippocampus drives vulnerability and resilience to chronic stress: The role of venlafaxine treatment

British Journal of Pharmacology, EarlyView.
Background and Purpose Neuronal plasticity enables the brain to adapt to internal and external demands by dynamically regulating synaptic connectivity and emotional circuitry. Impaired neuroplasticity represents a core pathophysiological framework of major depressive disorder, one of the leading causes of disability worldwide. Chronic stress is a major
